LNT2V822MSEJ

The LNT2V822MSEJ from Nichicon is a screw-terminal aluminum electrolytic capacitor in the LNT series designed for general-purpose power applications. It combines high capacitance (8.2 mF) with a 350 V rated voltage, a high ripple current capability, and a 105 °C endurance rating for robust performance in demanding DC bus and power-filtering roles.

Packaged in a radial can with screw terminals (φ90 × 150 L), this mass-production part targets designs that require large energy storage, sustained ripple handling, and extended operating life at elevated temperature.

Key Features

• High Capacitance & Voltage – 8.2 mF nominal capacitance at a 350 V rated voltage, providing significant energy storage for DC bus smoothing and bulk decoupling.
• High Ripple Current Capability – Low-frequency ripple current of 29.3 A (120 Hz) and high-frequency ripple current of 41.02 A (100 kHz) to support heavy AC ripple and switching loads.
• Extended Temperature & Life – Rated for operation from −25 °C to +105 °C with a rated life of 5,000 hours at 105 °C under rated ripple conditions.
• Robust Mechanical Termination – Screw terminal mounting in a radial can (φ90 × 150 L) for secure, serviceable connections and high-current bus integration.
• Electrical Performance – Capacitance tolerance of ±20% and a dissipation factor (tan δ) of 0.2 measured at 20 °C, 120 Hz for predictable AC loss characteristics.
• Leakage Current – Specified leakage current of 5000 µA for initial screening and design margin considerations.
• RoHS Compliant – Conforms to RoHS requirements for regulatory compliance in applicable regions.

Typical Applications

• Industrial Power Supplies – Bulk smoothing and DC-link storage for high-voltage power supplies where 350 V rating and high ripple current handling are required.
• Inverters and Motor Drives – Energy buffering and ripple suppression on DC buses serving power conversion stages with significant switching currents.
• UPS and Backup Systems – Bulk energy storage and damping of surge/ripple currents in uninterruptible power and backup modules operating at elevated temperatures.
• Commercial Power Electronics – General-purpose high-voltage filtering and decoupling in industrial and commercial equipment requiring long life at 105 °C.

Unique Advantages

• Large Energy Density: 8.2 mF at 350 V delivers substantial stored energy in a single component, reducing the need for parallel arrays.
• High Ripple Endurance: Rated ripple currents (29.3 A @120 Hz, 41.02 A @100 kHz) enable reliable operation with heavy AC and switching loads.
• Designed for Elevated Temperatures: 5,000‑hour life at 105 °C provides predictable aging and service life for high-temperature installations.
• Secure Screw-Terminal Mounting: Robust screw terminals simplify high-current connections and maintenance compared with leaded or PCB-only styles.
• Measured AC Loss: Dissipation factor (tan δ) of 0.2 at 20 °C, 120 Hz supports thermal and loss budgeting in power designs.
• Regulatory Compliance: RoHS compliance supports use in regulated product lines without additional material screening.
